The present study was an attempt to examine the relationship between EFL students' sense of self-efficacy and their pedagogical success. For this purpose, 150 female EFL students studying English in two institutes in Ardabil city were selected according to convenient sampling method. The selected learners were given a standard version of Oxford Quick Placement Test (OPT) which showed that the 150 participants were at the lower intermediate (n=47), upper intermediate (n=56), and advanced levels (n=47). The participants were also asked to complete the “Students' Sense of Efficacy Scale”. Then, the collected data were analyzed through SPSS version 25 and Pearson correlations and linear regressions were run to answer the research questions. The results revealed significant relationships between sense of self-efficacy and pedagogical success of the EFL learners at lower intermediate, upper intermediate, and advanced levels. Likewise, the results indicated that sense of self-efficacy predicted a significant amount of pedagogical success at lower intermediate, upper intermediate, and advanced levels of L2 achievement. The findings can have implications for the EFL classroom and can pave the way for further studies focusing on the relationship between other personality traits and EFL learners’ pedagogical success.
